VAPOR-CONDENSER.

Specification of Letters Patent.

Application filed December 21, 1906.

Patented June 2, 1908.

Serial No. 348,970.

To all whom it may concern:

Be it known that I, JOHN CALHOUN CLARK, a citizen of the United States, and a resident of Atlanta, Fulton county, State of Georgia, have invented certain new and useful Improvements in Vapor-Condensers, of which the following is a specification.

My invention relates to condensers and especially to such condensers as are adapted for cooling the gases in the manufacture of sulfuric acid, and my invention consists in a condenser having a series of superposed casings and transverse cooling tubes connected with each other and with a water supply as fully set forth hereinafter andas illustrated in the accompanying drawing, in which Figure 1 is a sectional elevation of a condenser embodying my improvements; Fig. 2, a sectional elevation on the line 2-2 Fig. 1; and Fig. 3, a sectional plan on the line 33 Fig. 1.

The upright structure A has double walls inclosing a chamber X extending the length of the structure, and the space between the inner wall 1 and the outer wall 2 is divided by horizontal partitions 3 into a series of superposed casings each inclosing a chamber 'y, which in case of a round structure is annular. Across the chamber X, and through the inner walls 1, extend, preferably horizontally, series of tubes 5 upon different parallel horizontal planes, each series communicating at opposite ends with one of the chambers y, or, where the structure is rectangular and there are separate chambers y at each side, the tubes 5 communicate each with chambers at op osite sides of the structure.

At the fbwer end of the structure an inlet opening 7 communicates with an inlet duct or pipe 8 and an outlet opening 9 at the top communicates with an outlet pipe 10, and in some cases a spray device 0 at the top of the chamber communicates with a water supply pipe 12 so that water is caused to fall in a spray or shower into the cross-tubes 5.

At the top of the structure is shown a pan B supplied with water from a supply pipe 14 and from which an overflow pipe 13 leads to the bottom of the uppermost chamber y, or the pipe 13 may lead directly from the pipe 14. From the top of the uppermost chamber y an overflow pipe leads to the bottom of the next chamber y, and the overflow pipe from the top of the latter leads to the bottom of the chamber y next below, and so on,

the overflow pipe 15 from the lowest chamber y leading to the sewer or other discharge duct.

Where the structure is round in cross section and the chambers y are not subdivided there is but one overflow and one inlet to .each, but when, as in the case of a rectangular structure, there is a series of chambers y to each of the four walls there is an overflow and inlet to each, or all those on the same level may have communicatin ports or necks with one inlet and one over ow to each series. The bottom of the chamber X has or is formed into a pan or basin Y provided with a discharge pipe 17 As thus constructed the gases or vapors to be condensed flow into the chamber X from the pipe 8 and coming in contact with the surfaces of the tubes 5 are thereby cooled and condensed and flow ofl through the discharge pipe 17, and when a spray is used the water thereof will combine with or cool the gases and vapors, and aid in condensing or will combine with or form a solution with the same, and the solution or mixture will collect in the pan Y and be conducted out by the pipe 17.

It will be seen that in each compartment or chamber y the colder water enters at the bot tom and as it becomes heated flows upward so that the direction of flow coincides with that resulting from the increase of temperature, although the body of water as a whole passes from the top of the structure downward; that a very extended cooling area is secured in a comparatively limited space; that the water can be circulated over this entire area with great rapidity; and that Water or any desired solution can be brought into direct contact with the gas or vapor in a finely divided condition, and aids in condensation and in securing a solution of the matter contained in the gas or vapor.

While the described apparatus is adapted for use as a condenser in many different applications, it is especially serviceable for use in the manufacture of sulfuric acid, where one or more of the structures is arranged to receive the gases from a ,Glover tower and between the usual chambers. In such case there is a frame-work K consisting of vertical osts and cross beams supporting casings of ead which with an inner lining 1 of lead, inclose the various chambers, the tubes 5 being of lead or lead covered.

Without limiting myself to the construction shown, I claim:

1. A condenser consisting of a series of superposed casings, each with a chamber, series of horizontal tubes 5, on different par allel horizontal planes each series communicating at the ends with different parts of its casing and pipes arranged to direct fluid from the top of one casing to the bottom of the casing below.

2. In a vapor condenser the combination of series of super osed horizontal tubes arranged transverse y of a chamber, a casing communicating with each end of each series of tubes, and pipes and connections arranged to direct water downward through the succeeding series of tubes but upward from the lower to the upper tubes of each series.

3. In a vapor condenser the combination of series of superposed horizontal tubes arranged transversely of a chamber, a casing communlcating with each end of each series of tubes, pipes and connections arranged to direct water downward through the succeeding series of tubes but upward from the lower to the upper tubes of each series and means for distributing liquid upon the tubes, and an inlet for gases at the bottom of the chamher.

4. The combination in a condenser, of series of casings enclosing a central chamber,

independent series of horizontal tubes con- JOHN CALHOUN CLARK.
